Fort Trašte was built by the Austro-Hungarian Empire near Tivat in Montenegro. Built on a hill between 1907–09, it overlooks the Bay of Trašte on one side and the plain of Tivatsko polje on the other. The fort was intended to secure the bay against possible landings from the sea. It was bombarded during World War I but sustained little damage. The collapse of the empire in 1918 led to the abandonment of the fort. It is now derelict but is still in fairly good condition externally, with its rotating gun cupolas.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
